12 Claims.

This application is a division of our prior application, Serial No. 42,342, filed September 26, 1935.

The invention relates to locomotive tenders,

and one object of the invention is to provide a streamline covered tender for locomotives which affords greater conveniences and advantages in servicing operations, eliminates loss of coal from the tender While in motion or being supplied with coal, back drafts in the cab and liability of freezing of coal in cold weather, and ensures greater cleanliness of operation of a train.

Another object of the invention is to provide novel and improved arrangement of and means for replenishing the coal bunker and water cistern of the tank with coal and water.

With these and other objects in view, the invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:--

Referring now more particularly to the draw ings, l designates a steam locomotive and 2 its tender of a construction embodying our invention. The locomotive 5 herein shown is of stream- 5.; line form and is provided for this purpose with (Cl. lil5231) a streamline covering comprising a co'wl portion 3 covering the boiler above the lineof the running boards 3 from the cab 4 to the forward end of the smokebox, a hood portion 5 extending at the front of the locomotive from the forward end of the cowl portion to the tip of the locomotive pilot, and side panels or skirts 6 extending longitudinally from the rear end of the cab to the hood and vertically from points below the level of the running boards downwardly to a sufiicient level to cover the ashpan, the major or a substantial portion of the running gear and other appurtenances ordinarily exposed to give an unattractive appearance to the locomotive and to cause wind resistance. The sides, roof portion and rear end wall of the tender 2 are also shaped to give a finished appearance and streamline effect thereto. The side panels of the locomotive, sides of the cab and side walls of the tender are so rem tively arranged as to be in longitudinal alinement when the locomotive and tender are travelingo'n a straight track, so as to secure as far as possible a smooth flow of the air along the sideof the locomotive and tender from end to end thereof. In order to make this straight line arrangement substantially continuous across the gaps between the sides and roofs of the cab and tender a construction of vestibule curtain or gap closing means is employed comprising an arched hood curtain H9 and side curtains I80, such as shown in our aforesaid application, Serial No. 42,342.

The tender 2 comprises a body or tank having the coal bunker or space M9 and water cistern or space lfiil enclosed by sheet steel side, front, rear and top walls m, I52, I53, and I54. The side walls 55! as previously stated lie in alinement with the side panels of the locomotive and extend down to the level of the lower edges of the panels 6. Said side walls, front, rear and top walls are formed of sheet iron or steel and are suitably united to each other and to an interior angle metal framing I55. As shown, the front wall M2 is provided with a coal gate or outlet I56 for the discharge of coal from the bunker. The major portion of the top wall or roof lli i lies in the same horizontal plane as the top of the cowling and roof of the locomotive cab and above the bunker space is provided with coal filling openings adapted to be closed by doors I51 arranged in transversely alined pairs. In rear of the bunker space is a water filling hole I53. normally closed by a hinged door i553, from which hole a duct or conductor ltll leads. to the Water space or cistern below. This hole i558 and the upper end of the d ct 116 at a level to permit the tender to be filled with facility from the high water spouts. Adjacent to the rear end of the tender the roof i5 3 is provided with a depressed platform portion it connected therewith by vertical walls l6! and between the filling hole :58 and the front of this platform portion Hit the roof is provided with a depressed alley or passageway ifiz open at its rear end adjoining the platform itl and connected at its sides and front end with the main roof by vertical walls 63 and 56 the floor 565 of said alley or passageway lying in the plane of the platform lBl. At the forward end of the alley or passage.- Way is a ladder H53 leading from the iioor M5 to the top of the roof. In the platform 65 is a water filling hole l6; normally closed by a hinged door H53, which hole is arranged at a level to permit the tender to be supplied with water from low Water spouts. The platform 56% provides a support on which an attendant may safely stand, and the passage lt2 and ladder H55 provide. a means whereby the attendant may readily reach the door IE9 and travel from the rear end of the tender over the top thereof to reach and operate the doors l5? when said doors are hand operated from the top of the tender. A ladder m9 and hand rails or rabs ill on the rear end wall of the tender, and suitably positioned hand rails or grabs ill on the walls 585 and E63, allow the attendant to travel up and down with convenience and safety between the usual steps H2 at the rear end of the tender and the passageway and roof top. Each door iii'i comprises outer and inner sections H3 and H4 hinged at their meeting edges centrally of the door, as at I15, the outer edge of the door section 813 being hinged to the roof, as at I76, and the outer edge of the door section El i being provided with a handle ll? whereby the doors may be raised and swung outwardly to open position, in which operation the door section i1 3 swings over upon the roof surface and the door section ll l over upon the underside of the door section H3, as shown in dotted lines in Fig. 10. Ihe hinged edge of the door section Fi l may have an extension H8 beyond the hinges M5 to lap over the door section I73 in the closed position of the doors to prevent entrance of snow and moisture at this point and the adjacent edges of the different doors of each series may be arranged to lap for the same purpose.

In the tender structure above described the doors i5? are adapted to be manually opened and closed from the top of the tender by means of the handles l H. In Figs. 13 to 15, inclusive, however. we have shown means for operating the doors either by manually operable or by fluid pressure operated power mechanism operated or controlled for operation by means located at the front of the tender and in the gangway between tender and locomotive. Referring to these figures, which show sets of operating devices for respectively simultaneously opening and closing each door or sets of doors 55? on each side of the center of the tender, it will be seen that a rocker shaft Kit is mounted on the tender beneath each door or set of the doors it? at each side of the tender and that each shaft carries a lifting arm 59 2 having a sliding slot and pin connection I95 with the underside of the overlying door section H3, such that rocking movements of the shaft from and back to a normal position will effect opening and closing movements of the door or doors 55? connected to its lifting arm, as shown in full and dotted lines in Fig. 15. At a suitable point on each shaft let within the tender is 9.

weighted arm I95 which counterbalances the weight of the doors actuated by said shaft so as to enable it to be easily operated. The forward end of each shaft I93 extends outwardly through the front wall of the tender and is exposed in the gangway space. On this end of shaft I93 is a toothed wheel or gear 1% which meshes with a toothed wheel or gear E9! on an operating shaft 598 to which is fixed an operating arm I99. The arm 599 is adapted to have applied thereto the socketed end 2% of an operating bar or lever Elli, whereby the shaft H38 may be rocked to impart door opening and closing movements to the shaft 593. The lever Zfil during this operation may be retained in engagement with the arm 599 by means of a pin 2532 passed through a keeper opening in the arm. The bar or lever 28! may be the ordinary grate shaker bar of the locomotive which may be interchangeably used for grate shaking and door operating actions. of this bar or lever the coal doors on either side of the longitudinal center of the locomotive may be operated by applying the lever to operate either shaft 193. If desired, the two shafts i523 may be coupled together by connecting means, such as From the foregoing description, taken in connection with the drawings, the construction of the tender will be readily understood without a further and extended description, and that the By means ing from the streamline enclosure of the bunker and water tank of the tender and the novel arrangement of filling doors adapting the tender, bunker and water tank to be supplied with coal and water and the. water to be supplied with greater ease from high and low level water spouts. Also it will be seen that novel means for operating the doors, closing the opening to the coal bunker so as to enable these doors to be readily and conveniently opened and closed by means, if desired, so arranged as to adapt the doors to be. operated without the necessity of the fireman or other attendant ascending to the roof of the tender. While the features of the invention are particularly designed to be employed in streamline tenders, it is to be understood that such features may be employed in tenders of other types, and that, while the structure herein disclosed is preferred, changes in the form, proportions and details of construction of the parts may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.
